Second step in converting substitute-command-keys to Lisp.

* lisp/help.el (describe-map-tree): New Lisp version of
describe_map_tree.
(substitute-command-keys): Update to use above function.
* src/keymap.c (Fdescribe_map): New defun to expose describe_map to
Lisp.
* src/keymap.c (syms_of_keymap): New variable 'internal--seen'; a
temporary kludge planned for removal.  New defsubr for Fdescribe_map.
* test/lisp/help-tests.el: Minor cleanups.
